- PR #52045: fix(safety): casefold credential path guards

A bug was identified where credential-path deny heuristics could be bypassed on case-insensitive filesystems (macOS/APFS, Windows) due to case-sensitive comparisons. The related items address this by applying casefolding to credential path deny-lists on affected platforms.
